行動ルールを用いた歩行者エージェントモデルによる対向流の相転移の分析

抄録

In this study, by using a simplified pedestrian agent model with eight behavior rules, we analyzed the phase transition of the counter flows and clarified the relationships between the probability of the diagonal stepping with the evasion rules and the density level. As a result, we classified six phases of the pedestrian flows: (1)Static Layered Flow; (2)Stable Layered Flow; (3)Emergence and Collapse of Layered Flow; (4)Chaotic Flow; (5)Incomplete Clogging; and (6)Clogging. We also confirmed the phase transitions and showed that the small deflection of the diagonal stepping directions affects these phases.
